[mythtv-users] MythTV freezes on Fedora

Hi there. I find your problem interesting since I am running into a
similar problem. This is my first Mythtv install (following Jarod's
guide which is very well done. Thanks Jarod!) Here is my system setup:
Asus A7N8X-X Nforce based mobo
Using both onboard sound and ethernet
X being displayed on the PVR-350
Latest ver of everything available by apt as of 20 mins ago.
So here's what is happening. When I either schedule a recording, or
tape something that is currently on, it records about 2 or 3 mins
(sometimes as much as 10-15 mins,) and then stops as if it is done
recording. I thought at first it might have been the 350 crashing the
frontend since that seems to be happening to other people. The frontend
is still running fine. I decide to check Mythweb, and it complains that
it can't connect to the backend server. I decided to restart the
backend, however, that doesn't solve the problem. Look at the
mythbackend.log files, and no errors show up. As it turns out, when I
restart mysql, things start working again for another 10 mins. So upon
searching through all the system logs including the mysql log, I have
only found this error in mysqld.log:
Cannot initialize InnoDB as 'innodb_data_file_path' is not set.
If you do not want to use transactional InnoDB tables, add a line
to the [mysqld] section of init parameters in your my.cnf
or my.ini. If you want to use InnoDB tables, add to the [mysqld]
section, for example,
innodb_data_file_path = ibdata1:10M:autoextend
But to get good performance you should adjust for your hardware
the InnoDB startup options listed in section 2 at
/usr/libexec/mysqld: ready for connections
Now my sql settings are whatever were setup during the install, and it
isn't used for anything else. While I'm unix and linux competant, I
know little about mysql. Does anyone have any ideas what is going on?
I'd be happy to provide any log files it that will help.
